I keep getting authentication requests. I’ve changed my Microsoft password but I’m still getting requests.

    Changing the Microsoft account password does not automatically stop repeated authentication prompts if cached credentials or tokens still exist on devices and apps.

    Use these steps on each affected device/app:

    1. Remove cached credentials (Windows)
      1. Open Control Panel → User Accounts → Credential Manager → Windows Credentials.
      2. Remove any entries that contain “Outlook”, “MicrosoftOffice15_Data:SSPI”, or “MicrosoftOffice16_Data:SSPI”.
      3. Restart Outlook or the Microsoft 365 app and sign in again with the new password.
    2. Clear saved tokens (macOS with Outlook)
      1. Quit Outlook and all Office apps.
      2. Open Keychain Access (Finder → Utilities → Keychain Access).
      3. Search for Exchange and delete all entries for the account.
      4. Search for adal and delete items of type MicrosoftOffice15_2_Data:ADAL:<GUID>.
      5. Search for office and delete Microsoft Office Identities Cache 2 and Microsoft Office Identities Settings 2.
      6. Restart Outlook and sign in again.
    3. Update Outlook / Office Install the latest updates for Outlook/Office so that stored credentials are handled correctly after password changes.
    4. Check authentication method If any app is still using Basic authentication to connect to Outlook.com or Microsoft 365, switch it to Modern authentication (OAuth) or use a client that supports OAuth. Basic authentication is being removed and can cause repeated prompts.

    If prompts continue, repeat the credential-clearing steps and verify that all devices (PCs, phones, tablets) are using the new password and Modern authentication.
